Rooting the moto droid using sbrecovery or clockwork mod.
Building cyanogen mod from source, getting gingerbread on the moto droid.
Also adb usage, the android emulator and that other cool thing I forgot about... yea I know I'm terrible.

For the tech nerds I think that if you do an episode on gingerbread update of a rooted phone you should also do a demo on how to bake and create something of gingerbread. Cooking is good for all people, techy or not.
